Description
Overview
GAOTek circuit contact resistance parameter tester is a high-precision and digital switch testing instrument. It adopts high frequency and high-power constant current switching power supply technology, which can measure micro ohm contact resistance. It is widely used to measure the contact resistance, loop resistance of various switches and electrical appliances, and the contact resistance of cables, wires and welds. It has accurate measurement data and stable performance, meeting the requirements of on-site high-voltage switch maintenance of electric power and power supply departments and loop resistance test of high-voltage switch factory. The output current and measuring resistance are output on the 7 in (17.7 cm) high brightness touch color LCD at the same time. The measuring results can be output voltage or stored in U disk. The power-off storage can meet the data query at any time.
